In video editing, what does hitting the 'Space' key function as?

In video editing, hitting the 'Space' key functions as the Play/Pause command. This dual functionality is crucial for editors, as it allows for easy control over the playback of video footage. When the video is playing and the Space key is pressed, it pauses the playback; pressing it again resumes the video from that point. This makes the workflow smoother, as editors can quickly pause to analyze a section of the video or resume playback without needing to navigate away from the keyboard. This consistent behavior of the Space key across most video editing software helps maintain a familiar and efficient editing environment.
